  • Patent number: 6745843
    Abstract: A completion assembly for use in a lateral well bore has a base pipe with a plurality of holes through the sidewall of the base pipe. Flow through the holes is regulated to produce an influx difference between the ends of the base pipe. Flow can be regulated by variably spacing or sizing the holes. Flow can also be regulated by selectively inserting a rod between adjacent splines located on the base pipe to cover and block the flow through certain holes in the base pipe. Flow can also be regulated using a rotatable sleeve adjacent to the base pipe such that rotation of the sleeve brings the holes and openings in the pipe and sleeve, respectively, into and out of alignment. A filter can be used to filter sand and other particulates. An erosion inhibitor can be used to extend the useful life of the assembly.

  • Patent number: 6688397
    Abstract: A system for expanding tubular structures. The system comprises a mandrel that is moved through the center of a tubular structure to increase the diameter of the tubular structure via deformation. The system utilizes an expansion device having a mandrel with multiple segments moved between a contracted state and an expanded state. In one embodiment, the mandrel segments are spring biased to permit a degree of independent movement of each mandrel segment with respect to the other mandrel segments.
